Function Documentation

c8_deinit()

void c8_deinit

(

C8 *

c8

)

Deinitialize graphics and free c8.

Parameters

c8	C8 to deinitialize

c8_init()

C8 * c8_init	(	const char *	path,
		int	flags
	)

Initialize and return a C8 with the given flags.

This function allocates memory for a new C8 with all values set to 0 or their default values, adds the font to memory, inititializes the graphics system, and returns a pointer to the C8.

Parameters

path	path to ROM file
flags	flags

Returns

pointer to initialized C8.

c8_load_palette_f()

int c8_load_palette_f	(	C8 *	c8,
		const char *	path
	)

Load palette from the given path into colors.

Parameters

c8	where to store the color codes
path	palette file location

Returns

1 if success

c8_load_palette_s()

int c8_load_palette_s	(	C8 *	c8,
		char *	s
	)

Load palette from the given string into colors.

Parameters

c8	where to store the color codes
s	string to load

Returns

1 if success

c8_load_quirks()

void c8_load_quirks	(	C8 *	c8,
		const char *	s
	)

Load quirk flags from string.

Parameters

c8	where to store flags
s	string to get quirks from

c8_load_rom()

int c8_load_rom	(	C8 *	c8,
		const char *	addr
	)

Load a ROM to c8->mem at path addr.

Parameters

c8	C8 to store the ROM's contents
addr	path to the ROM

Returns

1 if success.

c8_simulate()

void c8_simulate

(

C8 *

c8

)

Main interpreter simulation loop. Exits when c8->running is 0.

Parameters

c8	the C8 to simulate

c8_version()

const char * c8_version

(

void

)

Get the version of libc8.

Returns

const char* version string
